King 1 and King 2 oc's in Cas...19th mag???

[Jraymond]

So what you guys are trying to tell me, no one uses Uranometria DSFG. While the Willmann-Bell ads in SKy and Tel told me otherwise over the years.

I really suspect it's a misprint , 10th mag instead of 19th in both cases.

10th magnitude for a complete total integrated magnitude makes sense for King 1, but not King 2.
I trust the information in "Star Clusters" by Archinal & Hynes. If the DSFG differs, i'd discard what DSFG says.
Also, try NED and SIMBAD.
